Thank You Mr. Penner

Exhaust experts/engine experts - I need your valuable inputs here






My 10second quarter mile run

Exhaust, headers and flange, All fabricated by myself, welds were cleaned afterwards and heat shields were also fabricated

Running 100% RICH with DNA air filter

the torque is insane now, mileage is basically non existent, Only getting 23 miles per gallon or 10 KM per Liter


I have real-time air fuel ratio monitoring system installed as well, cost $500usd

Hello, Journeyman,
In stealth mode, it is as quiet as the stock mufflers. I have found this to be most useful on road trips when cruising around 3,000rpm. It's nice to
enjoy the ride and not listen to loud exhaust. I haven't noticed a real drop in performance in this mode, with the exception of how it revs.
Now in performance mode it has a deep authoritative presence when I get on it. I have been told it has a deep rumble, you know when I'm getting on it.
The engine revs to redline quickly as it pulls hard to 7,000rpm.
Push Button switch location, Left side.
This rotates the E-Valve 180-degs each push of the switch.

Nice install,Im impressed with how your finished exhaust turned out.
 
Would like to see dyno results between all the different collectors, would be interesting, would think each has a different number and effect.
 
Did you get the fuel numbers under control?
